WINDOW-SCREEN.

Patented Nov. 2, 1909.

the drawings by letter, A designates the sill of a window, B the jamb and C the lintel, all of the usual construction. Mounted between the jambs of the Window are the upper and lower sashes, designated respectively by letters D and D, between which is the usual parting strip (Z. F astened to the faces of the window jambs are the blind strips E to each of which are fastened the pins or studs F, the shank portion of each of which forms, 5 preferably, a bearing surface fora hollow roller F, thereby reducing the friction intermediate the pins or studs and the walls of the guide grooves G, formed in the vertical bars H of the screen H, to a minimum. Each of said bars H is rabbeted upon one face thereof and adapted to receive the guide strips I which, when fitted in place, have their outer faces flush with the faces of the screen.

Each of the bars H of the screen frame is recessed or slotted as at J, .afiording means whereby the screen may be swung outward when the slot comes opposite one of the studs or pins F. The bottom wall of each groove G formed in the screen bars H is recessed as at L, and L designates a spring fastened at one end within said recess, and having a curved portion projecting in the manner shown so as to contact with the end of one of the studs or pins F with suflicient frictional force, when the screen is at. its highest limit, to hold the same in such adjusted position. Projecting from the lintel .of the window is a stud or pin N which is adapted, when the screen is at its highest position, to engage a socket N formed in the upper marginal edge of the screen frame. Projecting also from the under edge of the lintel is a screen retaining strip 0 which is positioned outside the screen and serves as an additional means for holding the upper end of the screen from moving outward when raised to its highest position, said strip 0 forming, when the screen is raised and engaging the same, a lap joint, either one of these means being utilized for preventing the screen from moving outward.

Fastened'to the upper end of the screen is a plate Q, which overhangs and forms a closure to the groove G which is formed in the edge of the screen bar and adapted to rest upon the roller F mounted upon the upper of the studs or pins. F, it being understood that each vertical edge of thescreen In Fig. 5 of the drawings, I have shown a slight modification of the form of rabbet strip in which, instead of rabbeting thescreen frame entirely through the wall of the'slot or groove therein, I form a recess, preferably with a concaved wall as shown and adapted to receive a guide or rabbet strip R having a convexed edge conforming to the concaved wall of the rabbeted portion and with its other two edges flush with the face and edge of the screen frame.

In Fig. 6 of the drawings, I have shown a modified form of removing the screen from the window jambs, consistin of forming a slot T on the outside of t e screen, thus affording means whereby the screen may be removed by swinging the same out- .ward and in such position giving the same a downward movement, as will be readily understood. In order to hold the screen locked, in its lowest position, any suitable fastening means S may be applied thereto and adapted to engage the sill of the win- In operation, when it is desired to adjust the screen in place, the slots J are brought opposite one of the pins F, allowing the screen to be inserted intermediate the blind stops. The anti-friction rollers mounted upon the pins will serve as guides to the slots or grooves to allow the screen to be raised and lowered as an ordinary vertically movable window sash. \Vhen it is desired to hold the screen at its highest position, it is done by the spring L engaging frictionally the head or ends of the studs or pins F while the upper end of the screen will be held from lateral movement by means of the stud or pin N engaging the socket N or the retaining strip 0, either one or both of which may be employed. When it is desired to remove the screen from the window, it may be done by lowering the screen so that one of the slots or recesses J will come opposite the stud F, allowing the screen to be pushed outward. When the screen is adjusted to swing, the plates Q will rest upon the upper of the studs or rollers F forming bearing surfaces.

By'the provision of the rollers engaging thegrooves in the screen frame, the usual tongues are dispensed with and the friction between the screen and the guide rollers will be reduced to a minimum.

What I claim to be new is 1. In combination with a window frame, a screen frame having grooves in its'outer vertical edges, said grooves being closed at their upper ends, projections from the j amb ofthe window frame extending into said grooves and serving as guides to the frame, one wall of each of said grooves being recessed for allowing the screen to swing laterally.

2. In combination with a window frame, a screen frame having grooves in the outer vertical edges, said grooves having closures at their upper ends, guide studs projecting from the jamb of the window frame into said grooves and adapted to contact with said closures to form bearings upon which the screen is allowed to swing.

3. In combination with a window frame, a screen frame having grooves in its outer vertical edges, plates secured to the top of the screen and forming closures to said grooves, guide studs projecting from the jamb of the window frame and extending into said grooves, the upper of said studs adapted to form bearings upon which said plates rest to allow the screen, when at its lowest position, to swing outward.

4. In combination with a window frame, a screen frame having grooves in its'outer vertical edges, plates secured to the top ofthe screen and forming closures to said grooves, guide studs projecting from the jamb of the window frame and extending into said grooves, anti-friction rollers upon said guide studs, the upper of said rollers adapted to form a bearing upon which the screen swin s.

5. n combination with a window frame, a screen frame having grooves in its outer vertical edges, guide strips in rabbeted portions of the screen frame, plates forming closures to the upper ends of said grooves, studs projecting from the jamb of the frame and extending into said grooves and forming bearings upon which the plates rest as the screen swings.

6. In combination with a window frame, a screen frame having grooves in its outer vertical edges, guide strips in rabbeted portions of the screen frame, plates forming closures to the upper end of said grooves, studs projecting from the j amb of the frame and extending into said grooves and forming bearings upon which the plates rest as the screen swings, and means engaging frictionally the ends of said studs for holding the screen ele-' vated.

7 In combination with a window frame, a screen frame having grooves in its outer vertical edges, guide strips in rabbeted portions of the screen frame, plates forming closures to the 11 per end of said grooves, studs projecting rom the jamb of the frame and extending into said grooves and forming bearings upon which t e plates rest as the screen swings, means engatging frictionally the lower of said studs or holding the screen elevated. c

8. In combination with a window frame, a screen frame having grooves in its outerfvertical edges, guide strips in rabbeted portions the screen frame, plates forming closures the upper end of said grooves, studs prting from the j amb of the frame and eX- ding into said grooves and forming bears upon which the plates rest as the screen ings, means engaging frictionally the ver of said studs for holding the screen vated, and means for holding the upper d of the screen from moving laterally en in a raised position.

9. In combination with a window frame, a l een frame having grooves in its outer veral edges, guide strips in rabbeted portions the screen frame, plates forming closures the upper end of said grooves, studs proting from the jamb of the frame and exiding into said grooves and forming beargs upon which the plates rest as the screen ings, a spring fastened in a recess in the ttom wall of said groove and adapted to ntact with the ends of said studs to hold e screen in a raised position, and a projecn upon the lintel adapted to engage the per portion of the screen to hold the same om moving laterally.

10. In combination with a window frame, screen frame having grooves in its outer rtical edges, guide strips in rabbeted porus of the screen frame, plates forming closures to the upper end of said grooves, studs projecting from the jamb of the frame and extending into said grooves and forming bearings upon which the plates rest as the screen swings, a spring fastened in a recess in the bottom wall of said groove and adapted to contact with the ends of said studs to hold the screen in a raised position, and a strip projecting downward from the lintel and adapted to form a lap joint over the upper edge of the screen when raised.

11. In combination with a window frame, a screen frame having grooves in its outer vertical edges, closures to the upper ends of said grooves, the corresponding side walls of the grooves having slots therein, drag studs projecting from the jambs of the window and extending into said grooves, the upper of said studs forming bearings engaging the closures to the grooves for allowing the screen to swing, said slots allowing the ends of said pins to move therethrough.

In testimony whereof I hereunto affix my signature in the presence of two witnesses.
